Chrome Extension APIs

JavaScript APIs providing privileged access to Chrome browser functionality: manage windows, modify tabs, and control the extension lifecycle.

The Chrome Extension APIs are a comprehensive set of JavaScript interfaces, exposed under the `chrome.` namespace, that enable deep browser integration. Developers use these asynchronous methods to build powerful tools, accessing critical features like `chrome.tabs.create()` for new tabs or `chrome.action` for toolbar icon control. All modern extensions must adhere to the Manifest V3 standard, which mandates service workers and stricter permissions for enhanced security and performance.
